The Night They Raided Minsky's (1968)

To distance herself from her strict Amish family, naïve Rachel Schpitendavel (Britt Ekland) escapes to New York City to become a dancer. While Rachel's dances based on Biblical stories are too innocent for Minsky's Burlesque House, club-owner Billy Minsky (Elliott Gould) plans on using Rachel's routine to humiliate critics of his business. But trouble arises when partners in a comedy duo (Jason Robards, Norman Wisdom) compete for Rachel's affections.
